Abstract

The invention relates to an annular circular saw blade (8) with imaginary centre axis and with a plane of symmetry (19) which is perpendicular to the imaginary centre axis, an inner rim section (14) with a first drive surfaces (22) provided to work in conjunction, through friction coupling, with second drive surfaces (38) on a rotating drive unit (30); an outer rim section (15) with cutting devices and between them a web portion (16) with an underside (17) and a topside (18), with at least one of the said sides (17, 18) exhibiting at least a first annular bearing surface (25) provided to work in conjunction with a second annular bearing surface (45) on a support element (40, 41) for holding the saw blade in position. According to the invention the said first drive surfaces (22) are provided in a groove (20) in the inner rim of the saw blade.
